05: Acceptable high voltage for bypass mode 

Interface 

Setting 

 

Parameter 2: 

Set the acceptable high voltage for bypass mode. 

Setting range is from 231V to 276V and the default value is 
264V. 

 

06: Acceptable low frequency for bypass mode 

Interface 

Setting 

 

Parameter 2:

 Set the acceptable low frequency for bypass 

mode.   
50 Hz system: Setting range is from 46.0Hz to 49.0Hz. 
60 Hz system: Setting range is from 56.0Hz to 59.0Hz.
